Quizplus · Accepted Answer

When passing a class instance as an argument, the parameter variable becomes a reference to the object. This means that any changes made to the parameter variable within the method will also affect the original object outside of the method. Option A is incorrect because a copy of the object would not allow changes to be reflected on the original object. Option C is incorrect because objects in Java are not manipulated through their memory addresses. Option D is not a commonly used term in Java programming.
